The Official Organ of the Irish Genealogical Research Society was first published in April 1937. This publication covers from that very first issue up to Volume 8 in 1993. The Irish Genealogist, through many of its articles, allowed researchers gain access to material that in many cases was held in private collections, was otherwise inaccessible or lost, particularly following the fire in the Public Records Office in 1922.

Covering such diverse topics as family registers, abstracts of Diocesan Wills, monumental inscriptions, many important family genealogies, guides for those wishing to do their own genealogical research, as well as Ken Nicholls standard setting work on the Kavanaghs (1400  1700). These and much more are covered in over 5,000 pages of invaluable material, compiled in an easy to use and search format, using scans of the original volumes.
